Best Fuel System Cleaner – The Practical Buyer’s Guide

In order to give you the right knowledge to pick out your best option for a fuel system cleaner, it is important to have some background on these fuel additives.  Here we will do a break down on some of the important points, both as far as background and pointers on the way to use and select your perfect option.

What’s a Fuel Injector Cleaner and System Cleaner?

  • General Information

    fuel injector cleanerBefore delving too far into what a fuel injector cleaner is, let’s first go over the fuel injector itself. This part of your engine that delivers the correct amount of gasoline into the manifold, helping it to go from the liquid in your tank to the mist that works better for combustion.

    As you can no doubt guess, if your injector gets gunked up by foreign substances it won’t work as well and your vehicle won’t run as smoothly. There are a number of ways that these things could build up on your injectors, such as long periods of not being used or overheating.

    If foreign materials end up in your gas tank they can easily make their way to your injectors as well. Also, using poor quality fuels can cause build-up.

  • How Fuel Injector Cleaners Work

    A fuel system cleaner works by dissolving the build up in the lines and valves of your vehicle’s fuel system. It is generally applied by adding a quality fuel additive when you refuel your vehicle. The additive mixes with the fuel and works through the system. The build-up gets dissolved and is burnt off in the process of driving.

  • Main Chemicals Involved in the Best Fuel Treatments

    There are three main chemical compounds that you want to look for in your fuel system cleaner. Any bottle that claims to be a fuel cleaner that doesn’t tell you what it is made of should probably be shunned for something where you know what you’re getting.

    Polyisobutylene: This is commonly called PIB. It can be found in formulas for both gasoline and diesel additives and works to clean out build up and sediment. Some have even seen improvement in misfires and engine knock with this compound.

    Polyether Amine: You will probably find this one simply labeled PEA. This is a powerhouse compound, breaking down gunk that has solidified or is partially blocking lines. A major plus for this one is that there is no residue left in the system after use.

     Polyisobutylene Amine: This one is often called PIBA. It is similar to PIB, but it shines in reducing moisture. The downside to this compound is that since it is not great at cleaning the combustion chamber it should be used more in a maintenance role than the go-to when you need to knock out build up gunk.

  • Efficiency

    One issue with looking at these is determining how effective they are. Sure, you can just empty a bottle into your tank and you’ll probably think that you notice some improvement.

    But unless your car was really riding rough, you might not be sure if the improvement is there or in your mind. One thing to remember is that if you are dealing with the build up in your engine you will most likely need more than one application.

    Most bottles that you get will be a single-use, so you’ll have to consider the cost-efficiency of these for a number of uses weighed against fuel efficiency of your car.

  • Fuel Injector Cleaner vs Fuel System Cleaner

    While many times these are used interchangeably when discussing some of the products on the market, there is a bit of a difference. A fuel injector cleaner is designed to clean the built up gunk off that particular valve.

    This alone can improve the performance of your car. A fuel system cleaner goes more in depth. These products will end up helping to clean out fuel lines as well as the gunk on the valve. 

    In most cases, these are a better choice as they can improve the whole system instead of just on the component.

What Makes the Best Diesel Fuel Injector Cleaner

dieselDiesel is a rather dirty fuel, to begin with, so while you might argue that with quality modern gasoline a fuel cleaner isn’t necessary, but when it comes to diesel you are going to need to have one at one point or another. Luckily there are a number of cleaners that have been designed for diesel fuels.

Some cleaners will work in both gasoline and diesel engines, while others are formulated for just one type of engine.  You will want to double check that the style of cleaner that you end up selecting will work with your engine type.  If not, the best case is that the additive will just not work, but there is the possibility that it may cause some damage if it is not used properly.

How Do You Clean Fuel Injectors at Home?

There are a couple of options when it comes to cleaning out fuel filters at home. While you have the option to pay someone else to do the work, you can do the work yourself and save some money. The first option will no doubt give you a much cleaner system, but it will take work and skill.

You can purchase a fuel injector cleaner kit (like this one) and then remove your injectors. This method will require you to disconnect vacuum lines. This method means that you need to have the tools and skills to take out the injectors and then clean them. You will also need the confidence that you can get them back into your engine properly.

The other option is to use a fuel system cleaner. These only need you to put into the gas tank and let them do their work. This means that you don’t have to worry about not getting things properly aligned and you won’t have any downtime that you can’t drive your car.

At this point, we will also remind you about the oil filter change. This is as important as the fuel filter change and must be done regularly. Find out more here.

How Do You Use Fuel Injector Cleaner?

At a very basic level, a fuel injector cleaner is simple to use. You’ll want to add the fuel additive to the gas tank.  However, there are a few things that you need to consider.

First off, if you read the instructions on the bottle that you choose, you’ll see that each different companies recommend that you use a different amount with your tank.

You’ll also find that the instructions will specify a different tank size. That means that you will need to know the size tank of your particular vehicle. Some different companies will recommend the use of the entire bottle, while others ask to just use a small portion.

The latter means that you will need to measure out amounts as you add them into your tank.

Do Fuel Additives Really Work?

There was a time when fuel additives didn’t do much for you or your car. However, today the best fuel treatments can really give you a boost while driving. 

The first thing you will want to consider is the type of fuel additive you want to use based on what you want to accomplish.   One option is to go with an octane booster, these can boost performance.  We have covered these options in a previous article while debating about the best octane boosters on the market.

However, if you are looking to clean out your fuel system, which will, in the long run, boost your fuel efficiency, you will want to look at one of the modern fuel injector cleaners. 

An important thing in determining how well they work is to follow the instructions. Many people will just dump a bottle into their tank and then not do anything else for six months to a year.

For the full effect, you will need to run a number of treatments to get all the build-up out of your system. Once you accomplish that, you’ll want to continue to do a treatment every so often.

This will help to ensure that you don’t end up with a further build-up that robs performance.

Using Fuel Injector Additives When Your Car is Not Being Used

When your car is left without being used for an extended period of time the gas can start to break down. You’ll have to do something to deal without as that break down can foul the engine.

One option is to drain the tank. This means that you will have to have a system to drain the tank and then when you want to use the car you’ll need to have gas on hand.

Another option is to add a stabilizing additive. These types of fuel additive will keep the gas from breaking down for up to two years. 

While if you have a car that you only drive on the weekend you can just hop in and go. However, if you leave your car for a year or longer you will want to let your car idle for about 30 minutes prior to use.

What Does Fuel Treatment Cost?

fuel injector cleaner costOne thing that you need to consider is the amount that you are spending to keep your system clean. Some of the higher end fuels will have various cleansers and detergents included in them and may end up burning cleaner in your tank.

However, there is quite a bit of a jump when it comes to going this route.

There is, of course, the option of paying someone to clean out your car’s fuel injector system. If you take it to a professional they will take the system apart and make sure that everything is cleaned.

This can run between $50 and $80, but it also means that you won’t be able to use your car for a chunk of time and if your system is already clean you will be wasting that money.

One of the strong options of the fuel additive is the low cost. Each bottle runs between $10 and $20. Even if you have to do a few treatments in a row to ensure that your system doesn’t have any build up you’ll still end up saving money. Also, these types of solutions can end up working while you are driving your car, so you don’t have any downtime.

Now that you have a few reasons to pick a fuel system treatment the question falls to where to purchase your best option. You can go to a large store that has an automotive department, but they tend to have a limited selection. You can check your auto parts store and they might have a decent selection, but you are still tied to the options they felt like a stocking.

Perhaps a better choice is to go with an online option. There are lots of options out there, but a large trusted store like Amazon may be your best bet. With that kind of option you have a wide selection and competitive prices. Also, you can normally get a good deal on shipping so your choice of the best fuel system cleaner will show up right at your door.

This is a situation where you need to pay attention to some of the details on the label. First off you need to ensure that you have a product made to work with your fuel type.

After that, you’ll want to make sure you get your dosage right. A bottle might work with a 15-gallon tank or might only want you to add an ounce for every 20 gallons.

 Finally, you will need to understand that seeing an improvement in performance might take a few applications. Alternatively, a lack of improvement may be a sign that you have a clean fuel system, to begin with.

Best Fuel Treatment – The Bottom Line

By this point, you should have all the information that you need to make a choice as far as your pick for the best fuel system cleaner. One important thing to remember is that you make a selection that will work for your particular fuel type.

While many of our picks work with both gasoline or diesel, you can’t assume that a great gas option will also be the best diesel injector cleaner.

We highlighted six products that all would be stand out in their own right. The Techron Plus Fuel System Cleaner topped our list as the best product due to its quality and ability to help to get your car running at top-notch again.
